Elusion (impossible dodging game)

I'm a beginner developer that just started learning how to make iOS apps in late December. My first app, Elusion, just came out today. It has a minimalist design, it's about avoiding various shapes for as long as possible, and it gets trickier as the game progresses.https://itunes.apple.com/us/app/elus...mUvbUpU2446352

It might look boring from the screenshot, but it's far from it when everything's moving.

If you have an iPhone with iOS8, maybe you could try the game out and give me some constructive criticism.
Just go to the iTunes Store, and type in "Elusion"
